About the Project

Multnomah County has led the effort to replace this 90-year old Willamette River crossing with a new, seismically-sound structure that offers upgraded facilities for all users. Traffic on the new bridge is open. Major work on the bridge is complete.

This project is an ongoing effort by Multnomah County to replace this 90-year old Willamette River crossing with a new, seismically-sound structure that offers upgraded facilities for all users. Traffic on the new bridge is now open, though drivers should allow extra time to cross the bridge on weekdays due to construction.

Project News - Bridge is OPEN

Thank you for visiting the Sellwood Bridge Project website. The bridge project is complete and this website is no longer being updated. Later this year, after Multnomah County launches a Sellwood Bridge web page on the county website, visitors to this page will automatically be directed to the new county site.

More than 600 people gathered at the Oregon Convention Center Thursday evening to help the Daily Journal of Commerce pay tribute to more than 30 outstanding projects completed in 2016 in Oregon or Southwest Washington.

The annual competition, now in its 23rd year, is regarded as one of the Pacific Northwest’s most popular building industry events. This year’s competition drew more than 95 entries in 10 categories, including new construction of private, public, mixed-use and multifamily buildings, infrastructure and transportation projects.

The replacement of the Sellwood Bridge in Portland was named the 2017 Project of the Year. The honor is given to a project that earns the highest overall score in the competition. In giving the project an almost perfect score, judges gave nods to the project team, including general contractor Slayden-Sundt Joint Venture, T.Y. Lin International Group and project owner Multnomah County, for an outstanding effort coordinating many components, using DMWESB subcontractors effectively and tapping innovative solutions to overcome challenges.

T.Y. Lin International (TYLI), a globally recognized, full-service infrastructure consulting firm, announces that the Sellwood Bridge Replacement project (Sellwood Bridge) in Portland, Oregon, has received an Honor Award in the 2017 Engineering Excellence Awards competition of the American Council of Engineering Companies (ACEC). TYLI served as Prime Consultant, Final Design, on the fast-track project, working closely with the Project Owner, Multnomah County, design subconsultant CH2M, and Construction Manager/General Contractor, Slayden/Sundt Joint Venture. The 2017 Honor Award was presented to the TYLI team at the ACEC Engineering Excellence Awards Gala on April 25, 2017, in Washington, D.C.

The Sellwood Bridge across the Willamette River opened to traffic on February 29, 2016, and replaces a deteriorating fixed span structure built in 1925. The 1,976-foot-long bridge, 1,275 feet of which is a steel deck arch, features three arch spans that support the 63- to 90-foot-wide deck of the main river spans. The new, seismically resilient bridge carries two 12-foot-wide vehicular lanes, two 6.5-foot-wide bike lanes/emergency shoulders, and two 12-foot-wide shared-use sidewalks. TYLI also designed the bridge to accommodate future streetcar service.

The Sellwood Bridge contractor is working on punch list and erosion control tasks as construction wraps up.

TRAFFIC

West Side Trail Bridge: On February 23, the bridge that connects the west side regional trail with the south sidewalk of the Sellwood Bridge opened for public use. The bridge travels under the west end of the Sellwood Bridge.

Bridge Sidewalks: On weekdays from February 27 to March 10 workers will use a snooper manlift on the bridge sidewalks to perform work on the structure below the deck. Bicyclists and pedestrians will follow a short-detour around the manlift. Work will begin on the south sidewalk, then shift to the north. A second snooper will be in use on the sidewalks the week of February 27-March 3.

Hazard markers for old bridge pier that will be removed in summer 2017

Field Work Notice - February 17, 2017

The Sellwood Bridge contractor is working on punch list tasks as construction wraps up.

Question of the Week: Why the hazard markers in the river? Several people have asked us recently about two hazard markers rising from an object in the river near the bridge. The poles mark the location of a concrete river pier from the old Sellwood Bridge. This pier could not be removed during construction of the new bridge so it will be removed during the in-water work period this summer.

TRAFFIC

Hwy 43: There will be brief traffic delays on Tuesday, Feb. 21 during non-peak hours in the through lanes under the bridge as workers in a manlift adjust overhead signs.
